Programs missing after clean install of XP on Dimension C521

I have completed a clean install of Windows XP Media Center 2005 onto a new (bigger) hard drive on my Dell Dimension C521 desktop. The drivers are successfully installed and it all works fine on the new drive, except that several programs, which came pre-installed on the original drive, are missing, namely Roxio MyDVD LE and CD Creator, and Corel Snapfire.

 

How can I install these programs - I especially want the Roxio ones - on the new drive? I can't find them on the (red) Operating System re-installation disc. My sytem did not come with any discs for re-installing programs.

 

Any help would be appreciated.
